Ok i have given this a while and im afraid its not getting any better. I have been playing lotro lastnight and i was lagging quite a lot, my friend was skipping ahead of me all the time and my skills were taking a good 5 seconds to be used.
I got fraps on to check frames it was running between 100 and 250 fps, Latency was mostly balanced on 32 with 0.4% loss. I continued to play and for a short while it got better then all of a sudden it went really bad it was like walking in slow motion, my cursor was the same. My friends voice went very slow and choppy and my whole pc went very very slow.
Game became unplayable so ive just got off and everything started to speed up again.
Its just happened again today, was playing for a couple hours with no problems then out of the blue the same thing. i Checked all temperatures cpu barely reaching 50 gpu 62 and frames were bouncing between 100 and 150. This isnt a heating problem and its something i cannot find any information on. I was suggested by a friend my psu isnt sharing power correctly between cpu and gpu. Feels like im hitting a brick wall.
